5.3.3 Procedure
1. Input the optical signal.
2. Set the wavelength, resolution, and level scale.
3. Press
Single
to start the measurement.
4. When the name of the
F7
horizontal key is not
Application
, press
F8
,
and then press
F7
.
5. Press
f3 LED Test
to display the measurement result display field.
6. Press
f1 Cut Level
and input the value using the keypad or rotary
knob.
The Cut Level setting range is from 0.1 to 50.0 dB.
7. Press
f2 Power Cal
and input the corrected value of the total power
using the keypad and rotary knob.
The Power Cal setting range is from –10.00 to 10.00 dB.
8. Press
f3 Kσ
and select the factor of reference deviation using
f1
to
f5
keys, keypad, or rotary knob. The factor can be entered from 1.00 to
10.00.
When measuring the full half width (FWHM), set 2.35 σ.
9. Press
f7 Off
to finish the optical diode measurement.
